Explanation:
It was really not
about superheroes as on May 6 the much touted
Super Moon, the largest Full Moon of 2012,
rose over this otherwise peaceful harbor.
And no supervillains
were present either as boats gently
rocked at their moorings near the checkerboard
La Perdrix lighthouse
on the coast of Brittany, France.
But the rise of the Super Moon was preceded by a
Green Flash,
captured in the first frame of this
timelapse video recorded that night.
The cropped image of the frame, a two second long exposure, shows the
strongly colored flash left of the lighted buoy
near picture center.
While the Super Moon was enjoyed
at locations all around the world,
the circumstances that produced the Green Flash were more restrictive.
Green flashes for both
Sun and Moon
are caused by atmospheric
refraction enhanced by long, low, sight lines and strong atmospheric
temperature gradients often
favored by a sea horizon.
